Improved performance: React leverages Virtual DOM, which speeds up the development of web apps. Instead of updating all of the components again, as traditional web applications do, Virtual DOM examines the components’ prior states and updates only the objects in the Real DOM that have changed.
Reusable components: Components are the building parts of any React application, and a single app is typically made up of numerous components. These components have their logic and controls, and they can be reused across the program, reducing the development time significantly.
Unidirectional data flow: React follows a unidirectional data flow. As a result, developers frequently nest child components within parent components when developing a React app. Because data flows in a single path, debugging faults and determining where a problem arises in an application at any given time becomes easier.
Create both web and mobile applications: React is well-known for its usage in the creation of online applications, but that’s not all it can do.
React Native is a popular framework that is derived from React itself and is used to create stunning mobile applications. React may therefore be used to create both web and mobile applications.
Dedicated tools for easy debugging: Facebook has created a Chrome extension for debugging React applications. Debugging React web applications becomes much faster and easier as a result of this.
Features of React:
Virtual Document Object Model (DOM): The Virtual DOM is React’s lightweight version of the Real DOM. Real-world DOM manipulation takes much longer than virtual DOM manipulation. When the state of an object changes, Virtual DOM just updates that object in the real DOM, not all of them.
Architecture: In a Model View Controller(MVC) architecture, React is the ‘View’ responsible for how the app looks and feels. Model, View, and Controller (MVC) is an architectural pattern that divides the application layer into three parts: Model, View, and Controller. The model is responsible for all data-related logic, while the view is in charge of the application’s UI logic, and the controller serves as a link between the Model and the View.
Extensions: React is more than just a UI framework; it has a large number of extensions that cover the complete application architecture.
It aids with the development of mobile apps and allows for server-side rendering. React may be extended with Flux and Redux, among other things.
Data Binding: Since React employs one-way data binding, all activities stay modular and quick. Furthermore, because of the unidirectional data flow, nesting child components within parent components is usual when working on a React project.
Debugging: React applications are simple to test because there is such a large developer community. Facebook offers a browser extension that makes React debugging easier and faster.
Components in React:
Components are the building pieces of a React application, each of which represents a different part of the user interface. React divides the user interface into multiple components, allowing for easier debugging, and each component has its own set of properties and functionalities. Here are some of the Components’ features:
- Re-usability: A component used in one area of the application can be reused in another area. This aids in the development of the product.
- Nested Components: A component can be nested within another component.
- Render method: A component must define a render method that specifies how the component renders to the DOM in its most basic form.
- Passing properties: A component can also receive props. These are properties that its parent has handed to it to specify values.
